Title: Servo circuit for optical disk player
Inventor: YOKOTA HACHIRO
IPC: G11B19/12
Filed: 1988-08-05
Abstract: PURPOSE:To realize optimum control by providing a disk size sensor to discriminate a diameter of a disk, using an outputted signal and changing the transmitting characteristic of a driving circuit which rotates and rives a spindle motor. CONSTITUTION:A disk sensor 17 to discriminate the diameter of a compact disk CD1 is provided near the CD1. For a system controller 10, the cut-off frequency of an LPF15 and the direct current gain of a spindle driver 16 are switched by using the signal to be outputted from the sensor 17. Thus, when the CD, whose diameter is 12cm, is set to a player, the diameter of the set CD1 is discriminated by the sensor 17 and a discriminating signal is inputted to the controller 10. The cut-off frequency of the LPF15 and the direct current level of the driver 16 are switched by this discriminating signal and made optimum for the diameter 12cm CD. In the case of the CD, whose diameter is 8cm, operation is similarly executed. Then, in the case that any one of them is set, the optimum control of the spindle motor can be executed.

Title: Method for long-term verification of digital signature and device therefor
Inventor: ZAMEK STEVEN
IPC: H04L9/08
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a technique for extending a period, in which credibility and integrity of a digital signature can be accurately verified, beyond the expiration date of authentication related thereto. SOLUTION: This method effectively extends a verifiable term of a digital signature, namely, extends it fully beyond the expiration date of either or all of authentication on which this signature is dependent. In one embodiment mode, a technique called 'State save' to solve LTSV(long-term signature verification) is offered. This substantially needs the use of cryptographic information and enciphering technology, therefore, in addition to a document itself, PKI (Public Key Instructure) state 24 (for example, cryptographic information such as authentication, CRL, etc.), is stored by using archive mechanism. This information constitutes everything necessary for reproducing a signature verification processing afterward.  When a user desires re-verification of the signature on the document, LTSV server 26 reproduces an accurate state of PKI at the point when this document was submitted first. LTSV server 26 restores this state, and the signature verification process accurately executes the process which LTSV server 26 executed several years ago.

IPC: H04L12/58
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To display an image expressed by an image file even when that image file is attached to electronic mail received by a portable telephone. SOLUTION: An electronic mail file is received by a portable telephone and characters expressed by text data are displayed on the display screen of the portable telephone (step 62). When an image file is attached to the received electronic mail file (step 63), it is inquired from the portable telephone to a digital still camera whether the image of that image file can be displayed or not. When the image can be displayed on the camera, the image file is transmitted to the camera (step 67). The image expressed by the image file is displayed on the display screen of the camera (step 74).

Title: Power steering device
Inventor: SASAKI SHIYUUICHI
IPC: B62D5/083
Filed: 1982-11-08
Abstract: PURPOSE:To improve the durability by improving the arranging method of a lock pin coupled with a C-type spring and a reaction pin in a device maintaining a neutral position with the spring force of the C-type spring and applying a reaction force corresponding to the road resistance to a steering wheel. CONSTITUTION:When a steering operation is performed, a steering gear (not shown in the figure) is rotated through an inner sleeve 3, a pin 17, a torsion bar 15, a pin 16, and an input element 13. In addition, the inner sleeve 3 is relatively rotated against the input element 13, the assist pressure is fed to a power cylinder from a port 8 or 9, thus allowing the power steering. In this case, a C-type spring 23 applies the steering reaction force against the rotating force of a steering wheel. That is, when a reaction pin 24 provided in the radial direction depresses one end 23a side of the spring 23 in conjunction with the rotation of the said sleeve 3, the other end 23b is locked with a lock pin 25 extended in the axial diretion of the sleeve 3, thereby the spring 23 is expanded and the spring force at that time becomes the reaction force.

When, in the step 507, the number value Ne of revolutions of an engine is below the given discriminating number value NIDL of revolutions, a correction factor KIDL is set to a given value XIDLO in a step 508. It is decided that an engine is in a running region in that stable operation is difficult to make, and fuel-air mixture is forced into a rich condition. This enables stabilization of idle running of an engine.

Abstract: PROBLEM TO BE SOLVED: To revise a data speed in the case of communication in accordance with the moving speed of a mobile terminal. SOLUTION: A mobile terminal 3 receives each of radio waves sent respectively from land survey satellites 4-6 and measures its own mobile speed based on phase differences among the radio waves in the case of making communication with a base station 2 while moving a service zone 1 at a prescribed speed. Then the mobile terminal 3 requests communication at the maximum data transmission rate permitted by the mobile communication system in response to the mobile speed to the base station 2. The base station 2 makes communication with the mobile terminal 3 at a data transmission rate requested from the mobile terminal 3. Thus, stable communication is attained independently number of times of hand-off operations.

Title: Cleaning device
Inventor: JIYAN BARESU
IPC: G03G21/00
Filed: 1994-08-22
Abstract: PURPOSE: To increase the storage capacity of a cleaner thump (vessel). CONSTITUTION: A cleaning blade 20 contacts an image forming surface 11 of a photodetector drum 10. There is a waste tonner thump 30 behind the cleaning blade 20. Since a system only depending on auxiliary gravity replenishment to the thump (with no magnet) does not fill up the top section of the cleaner thump, it becomes a factor to cause the unefficient use of the cleaner thump and the much shorter service life of a CRU. The magnetic waste tonner is attracted into the area of the thump 30, which is not filled only with this gravity replenishment, by magnetic force generated by a magnet 40 so that the storage capacity of the cleaner thump can be increased.

Abstract: PROBLEM TO BE SOLVED: To improve strength of a thermal head by forming a printing face which is a front face of a protecting layer covering a front face of a heat-generating resistance body in a shape to swell like a projection, setting a reinforcing body to a rear face of a heat-generating part, and covering the reinforcing body with a supporting body of a resin or a resin mixed with inorganic material particles. SOLUTION: A heat-generating laminate part of a thermal head includes a protecting layer 1, a heat-generating resistance body 2, a common electrode 3a and an individual electrode 3b set at the heat-generating resistance body 2 and a supporting body 4. Moreover, a barrier layer 8 is provided to prevent substances from a heat-generating part 5 constituted of the electrodes 3a, 3b and the heat-generating resistance body 2 and the supporting body 4 from scattering.
